2.16.8 Residual risks during SINGLE PITCH loading/unloading (work cycle)
2.16.8.1 SINGLE PITCH loading/unloading (work cycle) – (Risk ID: 12.01)
IDENTIFICATION RISK ASSESSMENT
Stage: Use
Person: Operator
Area: Z02 Material loading/unloading area
Initial risk: HIGH
RESIDUAL RISK: LOW
PLr (EN 13849): d
SIL (EN IEC 62061): SIL2
ACCIDENT SCENARIO
Consequence: 1.3 Crushing
Situation: Loading and unloading piece/s to/from the table.
Event: Risk of crushing resulting from the closing of the piece support devices.
Body part: Hands, fingers.
RESIDUAL RISK
Risk of crushing resulting from the closing of the piece support devices.
LIMITATION MEASURES
Mechanical: During loading/unloading stages, two protection measures are implemented for
reducing the risk and remedy to any misconducts by redundancy. These measures
are:
- Adjusting of the piece support devices, carried out by the maintenance technician
during machine setup.
- Two different pressure values (PROTECTION MEASURE M10) during
loading/unloading and processing stages.
Electrical: Check of the closing pressure of the piece support device.
Informative: The closing of the piece support device is performed by pressing the specific pedal
button located near the table. Once the piece has been put in place, keep the
hands away from the piece support devices, then step on the pedal to effect the
closing, which occurs at a reduced force compared to that used during the
processing cycle.
The piece support devices must be exclusively adjusted by the maintenance
technician in two different manners, described in the manual chapter on controls
and use.
